Old Hardwood Floor Gallery !

We have put together a series of photos to illustrate the hardwood finishing process. This will be the 1st, of a series of articles, that will help describe this process. There are many different wood species, thickness’, profiles, applications and circumstances that will dictate the procedures for hardwood finishing success. We will demonstrate in this presentation, one of the many ways to achieve this goal. If you have questions or concerns about your own projects, please visit our Flooring Discussion Forum.

60 year old «Oak Flooring» 3/4″x 2 1/4″ T&G

We will start with a small T&G hardwood repair. The one piece of damaged hardwood flooring must be removed 1st, before we sand, so we start by cutting 2 parallel lines through the center of the damaged flooring piece. This dual center-cut will enable floor removal, without damage to the surrounding T&G flooring.

We remove the center piece and carefully extract the remaining 2 sides. Only the tongue side of the T&G hardwood flooring is nailed. All residue must be removed, down to the subfloor or underlayment. We then cut our new piece to fit, and remove the bottom side of the flooring groove and cut the end tongue off the new piece. We then proceed with fitting the new flooring. The «new» flooring tongue will fit in the «old» groove of the existing floor. We then use poly glue on the subfloor, and top nail the new piece in place.

Now here is our observation on this hardwood floor refinish job: This hardwood flooring looked terrible after removing the carpet and pad. Then we discovered the hardwood floor was sanded and finished by a homeowner or novice sander. There were stop marks everywhere throughout the room, including the closet. Stop marks are drum sanding marks created when the equipment operator hesitates or fails to raise the drum while the equipment is still running. To repair the sanding damage and get a flat floor, the hardwood flooring must be sanded at a 45deg angle, or what we call «1/4 cut» the floor. This step is necessary to flatten the existing cupping and sander marks. Notice the 8″ lines across the floor?

We then sand the hardwood flooring «with the grain», and rough paper, to sand out the remaining drum sanding marks in our flooring. We finish the drum sanding, with 80 grit, and we’re ready to edge sand the floor.

The edge sanding is accomplished with the same grit sand papers. Some finishers won’t go around the edges with different grit paper. They prefer to use fine paper and eliminate the 2nd go around. We then hook and hand sand the corners, where our floor sanders won’t reach. The «hook» is a specialized paint scraper, with sharpened metal «L» blade, designed to get in small places.

Now that our hardwood floor is sanded, edged and hooked, we’re ready to screen our hardwood floor for maximum smooooth! The screening process uses a graphite screen to remove minor scratches and marks that may have been left on the floor. The screen sanding will expose any sanding flaws and guarantee a high quality sanding job.

Now that we’re done with the vacume, and I tacked our new floor, we will apply our sealer coat for finishing. If we were staining this floor, for color, we would have several more sanding steps prior to applying the stain. We will address this procedure in our ongoing articles.

The finish system used in this floor finishing example is 3 part. We are using a universal sealer to achieve the color and depth of 2 part oil based systems. The 2nd coat (finish) is applied over the universal sealer after buffing and tacking the floor. The water-based finish is allowed to dry overnight.

The next day our hardwood floor finish is screened with 180 grit. We then vacume and tack the floor anticipating the final coat and finish of our «new looking» floor.

Now we are ready to apply our Bona floor finish. We use an 18″ foam applicator and 10″ trim pad for the edges. We pull the poured-out finish, across the floor, with the grain, in 14″ to 16″ passes. We snowplow the finish to the dry side of our floor, to keep a «wet» edge for the next pass. We use this procedure for all the water-based finishes we use. We will discuss oil-base procedures in an upcoming article.

We have now completed our hardwood floor finishing project. I hope you enjoyed our presentation. We will announce all our new flooring projects and presentations in our FloorUSA newspage!
